Ten years performance guaranteed warranty

Periodically clean the threads and o-rings with a lint free cloth and apply a thin coating of EagleTac synthetic grease to the o-rings and threads. After prolonged exposure to moisture, the head and batteries should be removed, inspected, and dried. Do not touch or attempt to clean the reflector, as it will scratch the reflective coating permanently.

  1. The AA power house Review Rating

    Posted by Alex Gheorgheos on 10th Feb 2015

    If your looking for power in a affordable, compact and easy to use flashlight, look no further then the EAGLETAC GX25A3. This compact little light pushes out 1116LM powered by 3 AA batteries, whitch is outstanding. With a peak beam intensely of 20,100 with the XM-L2 version, your getting great throw and not to mention very useful spill too, the dark doesn't stand a chance with the GX25C2 in hand. Build quality is superb on this light, Eagletac manufactures their products with great craftsmanship and design. The light feels solid in your hand and can definitely stand up to abuse. My seven year old has dropped the light more times then i can count and its still working flawlessly. The GX25A3 comes with a spare tailcap whitch has a rear clicky switch integrated into it for even faster and easier activation, no more feeling around for that side switch. This flashlight comes in both cool white and neutral white for better colour identification. The cool white may have a bit more output when compared to the neutral tint but the warm tint can be more useful in many situations. I was so impressed with this light, i picked up both. Using 2500mah rechargeable 14500's I was able to achieve close to two hours until the lowest power setting kicked in. Thats better run time then sone other more expensive flashlights with bigger cells that are equally as bright.

    So if your looking for a well made, well priced flashlight thats super bright, with great run time. Then this Eagletac GX25A3 might just be what your looking for.i give this light a 5/5
